WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 308,680,'dated December 2, 1884.

Application filed August 20, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, Aneusr LINDGREN, of Moline, in the county of Rock Island and State of Illinois, have invented certain Improvements in XVheeled Plows, of which the following is a specification.

This invention relates to that class of wheeled plows in which a mold-board plow is secured firmly but adjustably to a frame carried upon wheels. It is designed more particularly for use in those plows in which the frame is carried by a wheel on the landside, a wheel carried in the new furrow behind the plow, and a swiveled leading-wheel which travels in advance of the plow in the preceding furrow, as illustrated, for example, in the patent granted to J. W. Bartlett, April 25, 1884, No. 296, 720.

- It is the aim of the present invention to secure the lateral adjustment or deflection of the plow with respect to the leading-wheel and draft devices, in order that it may be caused to take more or less land, and that the plow may be operated by two or three horses driven abreast, as the character of the soil may render necessary.

To this end the invention consists, essentially, in combining with the plow frame or beam and the leading-wheel a swivel-joint, constructed as hereinafter explained, to permit the'axle of the leading-wheel to be adjusted to the right or left with respect to the frame or beam.

Referring to the accompanying drawings, Figure 11s a perspective view of a plow having my imp rovement embodied therein. Fig. 2 is a top plan view of the improved coupling. Fig. 3is alongitudinal vertical section through the center thereof. Fig. 4 is a cross-section on the line 2 z.

Referring to the drawings, A represents a horizontal frame or beam sustained by three wheels, B, O, and D. The first is arranged to travel in the newly-formed furrow, the second to travel on the unplowed land, and the third to travel in advance of the plow in the furrow last completed. The land-wheel'O is mounted on a crank-axle, whereby it maybe adjusted vertically. The leading-wheel D is mounted on one end of the overhung axle, the inner end of which is attached to a swiveling plate, G,

connected by a vertical pivot-pin or kingbolt, H, to a draft-head, WV, which is bolted firmly to the front of the frame, this construction permitting the axle and, the leading-wheel to swing horizontally. Around the inner end of the axle there is journaled a plate, R, to which the draft pole or tongue is firmly bolted, this connection permitting the tongue to swing vertically, while at the same time it iscaused to control the swiveling action of the wheel. Draft devicesJ are swiveled to the lower end of the king-bolt, and connected by a lateral brace, T, with the outer end of the axle, where by the draft is caused to assist in maintaining the wheel in the proper position. An ordinary mold-board plow, E, is connected at its heel end by a horizontal pivot to the lower extremity of an arm, a, attached rigidly to and extending downward from the main frame or beam A, this connection permitting the point of the plow to be raised and lowered. At its front the plow is provided with a rigid standard, V, which is extended upward through a vertical slot in the frame or beam, and connected by intermediate devices to a hand-lever, X, which is also connected to the shaft of the land-wheel, the one lever serving to effect simultaneously the vertical adjustment of the plow-point and the land-wheel.

The foregoing parts are constructed and arranged to operate in essentially the same man nor as in the Bartlett patent before alluded to, and, with the exception of the peculiar construction of the draft-head hereinafter described, they are foreign to the present invention.

In the practical operation of the patented plow in the field it has been found desirable to provide a means of adjusting the forward end of the frame or beam A laterally with respect to the king-bolt and without changing the adjustment of other parts. To this end I connect the draft-head W with the frame or beam A by means of a vertical pivot in such manner that it may swing sidewise, and provide it with a locking device, bywhich it ma'y be held in the position required. The preferred form of the parts is represented in Figs. 2 and 3. The draft-head'lV is made of considerable length, with a vertical tubular sleeve or post, 0, at the forward end to receive the king-bolt, and with a plate, (1, extending It is manifest that my improvement may thence backward to receive the vertical pivotbe employed in connection with plows which pin 6, which extends downward through a have wheels at both ends of the leading-axle, plate, f, bolted within the forward end of the and that the details of the leading-wheel and frame or beam A.
